2 Application For the operation of Siemens 2-port and 3-port valves: Type series VVG mm stroke As control or shutoff valves in heating and ventilation systems. In conjunction with the ASK30 mounting kit, the former Landis & Gyr-valves with 4 mm or 5.5 mm stroke can also be operated: X3i.., VVG45.., VXG45.., VXG46.., VVI51 Functions Function Description Type 3-position control Modulating control Positioning signal and characteristic changeover Position feedback U Calibration Detection of valve seat Foreign body protection Forced control Z (Z mode) A 3-position signal drives the actuator via connection terminals Y1 or Y2. The desired position is transmitted to the valve. The modulating positioning signal drives the actuator steplessly. The positioning signal range (DC V / DC ma / ) corresponds in a linear manner to the positioning range (fully closed...fully open, or % stroke). Setting the DIL switches. Factory setting SAT..: Characteristic curve: lin = linear (switch at "ON") Positioning signal: DC V (switch at "OFF") Signal, returned to acquire the position via an input. Conduct during initial commissioning. The actuator deploys to the top and bottom end position; measured values are saved. Actuators have power-dependent seat detection. After calibration, the exact valve stroke is filed in the actuator s memory. After detection of clogging, 3 attempts are made to overcome clogging. If the attempts made are unsuccessful, the actuator continues to follow the positioning signal within the restricted range only (LED continues to blink red). Forced control serves for overriding automatic mode and is implemented in the structure. SAT31.. Types Type Stock no.

Observe national provisions and comply with the appropriate safety regulations. Engineering Installation SAT position actuators must have their own controller, see "Connection diagrams". Up to 10 actuators can drive in parallel on a controller output with a rating of 1 ma. Modulating actuators have an input impedance of 100 k. Mounting positions Indoor use Outdoor use 1) 1) Requires the weather shield ASK39.2. Degree of protection of housing IP54 remains unchanged. 4

5 Maintenance The SAT.. actuators are maintenance-free. Mounting: Do not touch the valve coupling if the components (valve/pipes) are hot If necessary, disconnect electrical connections from the terminals The actuator must be correctly fitted to the valve before recommissioning. Disposal The device is considered an electronics device for disposal in terms of European Directive 2012/19/EU and may not be disposed of as domestic garbage. Dispose of the device through channels provided for this purpose. Comply with all local and currently applicable laws and regulations. Warranty Technical data on specific applications are valid only together with Siemens products listed under "Equipment combinations". Siemens rejects any and all warranties in the event that third-party products are used. Note When using the actuators in connection with valves of other manufacture, correct functioning must be ensured by the user, and Siemens will assume no responsibility.
